- the present disclosure describes systems and methods that facilitate dynamic command management in a network interface controller (NIC).
- NIC network interface controller
- the NIC allows a host to communicate with a data-driven network.
- the embodiments described herein solve the problem of efficiently transferring commands to a NIC by (i) facilitating a command queue in the host device and an internal command buffer in the NIC for large-scale and low-latency command transfers, respectively, and (ii) dynamically selecting between the command queue and internal buffer for receiving a command.
- a host device of a NIC can issue a command for a data operation (e.g., a“GET” or a“PUT” command of remote direct memory access (RDMA)) to the NIC. Consequently, the host device can transfer the command (e.g., a direct memory access (DMA) descriptor of the command) to the NIC.
- the host device may store the commands in a command queue of the host device. The host device may maintain the command queue in the memory of the host device.
- the NIC can request the command from the host device.
- the processor of the host device can then transfer the command to the NIC.
- This read-based approach is based on the NIC accessing the memory of the host device. Therefore, the read-based approach can be referred to as the memory-based command path.
- the memory-based command path can allow large-scale transfer to the NIC and facilitate efficient bandwidth utilization of the internal bandwidth of the host device.
- the memory-based command path can have high latency for the command transfer because the interface system (or processor interface) can be accessed multiple times for accessing the command.
- the host device may transfer commands associated with small amounts of data to an internal command buffer of the NIC.
- the processor of the host device may write in the internal buffer of the NIC.
- This write-based approach can provide data transfer with low latency. Therefore, the write-based approach can be referred to as the low-latency command path.
- the low-latency command path can limit the volume of transfer since the internal buffer of the NIC can have limited capacity.
- the NIC can combine both approaches to facilitate an efficient transfer rate with low latency.
- the host device may maintain a command queue for a respective flow of commands (e.g., based on traffic class) in the memory of the host device. If an application issues a command for the NIC, the command can be stored in a corresponding command queue. The host device can then notify the NIC regarding the new command by advancing a write pointer. Since any application may write in the command queue, this approach can be independent of the application. The NIC can then issue a read operation to the command queue and advance a pre-fetch pointer of the queue. When the data is returned, the NIC can process the command and advance a read pointer.
- commands e.g., based on traffic class
- the host device may insert a command into the internal buffer of the NIC.
- the NIC may maintain an internal buffer for a respective command queue of the host device.
- the buffer can have a fixed size that may host a limited number of commands. Since the command can be directly written into the internal buffer, the NIC can avoid a round trip data exchange via the internal communication channel (e.g., a peripheral component interconnect express (PCIe) channel). In this way, the NIC can reduce the latency of issuing commands to the NIC. By dynamically switching between the command paths, the host device can select a command path that can efficiently transfer commands.
- PCIe peripheral component interconnect express
- One embodiment of the present invention provides a NIC that can be equipped with a host interface, an arbitration logic block, and a command management logic block.
- the host interface can couple the NIC to a host device.
- the arbitration logic block can select a command queue of the host device for obtaining a command.
- the command management logic block can receive the command via the host interface and determine whether an internal buffer associated with the command queue includes a command. If the internal buffer includes the command, the command management logic block can obtain the command from the internal buffer. On the other hand, if the internal buffer is empty, the command management logic block can obtain the command from the command queue via the host interface.
- the command management logic block can provide the host device one or more of: (i) processing information associated with the internal buffer, and (ii) state information comprising a read pointer of the command queue.
- the command management logic block can determine that the command queue has a new command based on the advancement of a write pointer of the command queue.
- the arbitration logic block can select the command queue from a plurality of command queues in a memory of the host device.
- the NIC can also include a corresponding internal buffer for a respective command queue.
- the command management logic block may drop a new command received from the host interface and destined for the internal buffer upon determining one or more of: (i) insufficient capacity in the internal buffer to accommodate the new command, and (ii) the command queue is not empty.
- the command management logic block in response to receiving the new command, can advance a write pointer of the command queue, thereby determining the presence of a command in the command queue.
- the command management logic block can advance a pre-fetch pointer of the command queue upon requesting the command and advance a read pointer of the command queue upon receiving data associated with the command.
- the host interface can be a peripheral component interconnect express (PCIe) interface. The command management logic block can then obtain the command from the command queue based on a PCIe read.
- PCIe peripheral component interconnect express
- the command can include an RDMA command.
- One embodiment of the present invention provides a computer system that can include a memory device, a host interface, and a command management system.
- the memory device can store a command queue.
- the host interface can couple a NIC, which can maintain an internal buffer associated with the command queue.
- the system can write a command to the command queue and determine, based on states of the command queue, whether the internal buffer can accept the command. If the internal buffer can accept the command, the system can write, via the host interface, the command into the internal buffer. On the other hand, if the internal buffer cannot accept the command, the system can inform the NIC, via the host interface, that the command has been written into the command queue.
- the state of the command queue indicates whether the command queue is empty.
- the system can obtain statistics associated with the performance of the internal buffer and speculatively determine, based on the obtained statistics, whether the command queue is expected to be empty.
- informing the NIC can include advancing a write pointer of the command queue.
- the memory device can store a plurality of command queues.
- the system can write a plurality of commands into the command queue based on a granularity of allowed writes into the command queue.
- the system can advance a write pointer of the command queue according to the granularity.
- the system can select the command in the command queue as a backup command.
- the NIC can obtain the command from the command queue via the host interface if the command has been dropped at the internal buffer.
- the host interface can be a PCIe interface.
- the system can then write the command into the internal buffer based on a PCIe write.
- the command can include an RDMA command.

- IB InfiniBand
- a switch can have edge ports and fabric ports.
- An edge port can couple to a device that is external to the fabric.
- a fabric port can couple to another switch within the fabric via a fabric link.
- traffic can be injected into switch fabric 100 via an ingress port of an edge switch, and leave switch fabric 100 via an egress port of another (or the same) edge switch.
- An ingress link can couple a NIC of an edge device (for example, an HPC end host) to an ingress edge port of an edge switch.
- Switch fabric 100 can then transport the traffic to an egress edge switch, which in turn can deliver the traffic to a destination edge device via another NIC.

- NIC 202 can implement both eager protocol and rendezvous protocol for MPI, thereby offloading the corresponding operations from the host.
- NIC 202 can include PUT, GET, and Atomic Memory Operations (AMO).
- NIC 202 can provide reliable transport. For example, if NIC 202 is a source NIC, NIC 202 can provide a retry mechanism for idempotent operations. Furthermore, connection-based error detection and retry mechanism can be used for ordered operations that may manipulate a target state. The hardware of NIC 202 can maintain the state necessary for the retry mechanism. In this way, NIC 202 can remove the burden from the host (e.g., the software). The policy that dictates the retry mechanism can be specified by the host via the software, thereby ensuring flexibility in NIC 202.
- host e.g., the software
- NIC 202 can facilitate triggered operations, a general-purpose mechanism for offloading, and progression of dependent sequences of operations, such as bulk data collectives.
- NIC 202 can support an application programming interface (API) (e.g., libfabric API) that facilitates fabric communication services provided by switch fabric 100 of FIG. 1 to applications running on host 116.
- API application programming interface
- NIC 202 can also support a low-level network programming interface, such as Portals API.
- NIC 202 can provide efficient Ethernet packet processing, which can include efficient transmission if NIC 202 is a sender, flow steering if NIC 202 is a target, and checksum computation.
- NIC 202 can support virtualization (e.g., using containers or virtual machines).
- FIG. 2B shows an exemplary architecture of a NIC.
- the port macro of HNI 220 can facilitate low-level Ethernet operations, such as physical coding sublayer (PCS) and media access control (MAC).
- NIC 202 can provide support for link layer retry (LLR).
- Incoming packets can be parsed by parser 228 and stored in buffer 229.
- Buffer 229 can be a PFC Buffer provisioned to buffer a threshold amount (e.g., one microsecond) of delay bandwidth.
- HNI 220 can also include control transmission unit 224 and control reception unit 226 for managing outgoing and incoming packets, respectively.
- NIC 202 can include a Command Queue (CQ) unit 230.
- CQ Command Queue
- CQ unit 230 can be responsible for fetching and issuing host side commands.
- CQ unit 230 can include command queues 232 and schedulers 234.
- Command queues 232 can include two independent sets of queues for initiator commands (PUT, GET, etc.) and target commands (Append, Search, etc.), respectively.
- Command queues 232 can be implemented as circular buffers maintained in the memory of NIC 202. Applications running on the host can write to command queues 232 directly.
- Schedulers 234 can include two separate schedulers for initiator commands and target commands, respectively. The initiator commands are sorted into flow queues 236 based on a hash function. One of flow queues 236 can be allocated to a unique flow.
- CQ unit 230 can further include a triggered operations module (or logic block) 238, which is responsible for queuing and dispatching triggered commands.
- Outbound transfer engine (OXE) 240 can pull commands from flow queues 236 in order to process them for dispatch.
- OXE 240 can include an address translation request unit (ATRU) 244 that can send address translation requests to address translation unit (ATU) 212.
- ATU 212 can provide virtual to physical address translation on behalf of different engines, such as OXE 240, inbound transfer engine (IXE) 250, and event engine (EE) 216.
- ATU 212 can maintain a large translation cache 214.
- ATU 212 can either perform translation itself or may use host-based address translation services (ATS).
- OXE 240 can also include message chopping unit (MCU) 246, which can fragment a large message into packets of sizes corresponding to a maximum transmission unit (MTU).
- MCU message chopping unit
- MCU 246 can include a plurality of MCU modules. When an MCU module becomes available, the MCU module can obtain the next command from an assigned flow queue. The received data can be written into data buffer 242. The MCU module can then send the packet header, the corresponding traffic class, and the packet size to traffic shaper 248. Shaper 248 can determine which requests presented by MCU 246 can proceed to the network.
- the selected packet can be sent to packet and connection tracking (PCT) 270.
- PCT 270 can store the packet in a queue 274.
- PCT 270 can also maintain state information for outbound commands and update the state information as responses are returned.
- PCT 270 can also maintain packet state information (e.g., allowing responses to be matched to requests), message state information (e.g., tracking the progress of multi-packet messages), initiator completion state information, and retry state information (e.g., maintaining the information required to retry a command if a request or response is lost). If a response is not returned within a threshold time, the corresponding command can be retrieved from retry buffer 272.
- PCT 270 can facilitate connection management for initiator and target commands based on source tables 276 and target tables 278, respectively. For example, PCT 270 can update its source tables 276 to track the necessary state for reliable delivery of the packet and message completion notification. PCT 270 can forward outgoing packets to HNI 220, which stores the packets in outbound queue 222.
- NIC 202 can also include an IXE 250, which provides packet processing if NIC 202 is a target or a destination.
- IXE 250 can obtain the incoming packets from HNI 220.
- Parser 256 can parse the incoming packets and pass the corresponding packet information to a List Processing Engine (LPE) 264 or a Message State Table (MST) 266 for matching.
- LPE 264 can match incoming messages to buffers.
- LPE 264 can determine the buffer and start address to be used by each message.
- LPE 264 can also manage a pool of list entries 262 used to represent buffers and unexpected messages.
- MST 266 can store matching results and the information required to generate target side completion events. An event can be an internal control message for communication among the elements of NIC 202.
- MST 266 can be used by unrestricted operations, including multi-packet PUT commands, and single-packet and multi-packet GET commands.
- parser 256 can store the packets in packet buffer 254. IXE 250 can obtain the results of the matching for conflict checking. DMA write and AMO module 252 can then issue updates to the memory generated by write and AMO operations. If a packet includes a command that generates target side memory read operations (e.g., a GET request), the packet can be passed to the OXE 240.
- NIC 202 can also include an EE 216, which can receive requests to generate event notifications from other modules or units in NIC 202. An event notification can specify that either a full event or a counting event is generated. EE 216 can manage event queues, located within host processor memory, to which it writes full events. EE 216 can forward counting events to CQ unit 230.
- FIG. 3A shows an exemplary dynamic command management process in a NIC.
- a host device 300 can be equipped with a NIC 330.
- Device 300 can include a processor 302, a memory device 304, and an interface system 306.
- An HI 332 of NIC 330 can be coupled to interface system 306 of device 300.
- HI 332 can be a PCIe interface
- interface system 306 can be a PCIe system that provides a slot for HI 332.
- NIC 330 can also include a command queue unit 334 for managing incoming commands from device 300, as described in conjunction with FIG. 2A.
- device 300 can issue a command 320 for an operation (e.g., an RDMA operation).
- host 300 may generate a descriptor of command (e.g., a DMA descriptor) and transfer command 320 to NIC 330.
- command 320 is one of a large number of commands
- device 300 can store command 320 in a command queue 312 in memory device 304.
- NIC 330 can request a command from device 300.
- processor 302 can transfer command 320 to NIC 330 via HI 332.
- NIC 330 can read commands from memory device 304 of host 300. This memory-based command path can allow large-scale command transfer to NIC 300, thereby facilitating efficient bandwidth utilization of interface system 306.
- the memory-based command path can have high latency for the command transfer because interface system 306 can be accessed multiple times for accessing command 320.
- device 300 may transfer command 320 to an internal command buffer 314 in NIC 330.
- processor 302 may write in internal buffer 314.
- This low- latency command path can provide data transfer with low latency.
- the low-latency command path can limit the volume of transfer since internal buffer 314 can have limited capacity.
- NIC 330 can combine both command paths to facilitate an efficient transfer rate with low latency.
- device 300 may maintain a plurality of command queues, each for a respective flow of commands, in memory device 304.
- Command queue 312 can be one of the command queues.
- command 320 can be stored in command queue 312.
- Device 300 can then notify NIC 330 regarding command 320 by advancing a write pointer of command queue 312.
- NIC 330 can then issue a read operation to command queue 312 via HI 332 and advance a pre-fetch pointer of command queue 312.
- NIC 330 can process command 320 and advance a read pointer of command queue 312.
- command queue 312 may insert command 320 into internal buffer 314.
- NIC 330 may maintain an internal buffer for a respective command queue of device 300.
- Internal buffer 314 can be managed by command queue unit 334.
- Internal buffer 314 can have a fixed size that may store a limited number of commands. Since command 320 can be directly written into internal buffer 314, NIC 330 can avoid a round trip data exchange with processor 302 via interface channel 306. In this way, internal buffer 314 can reduce the latency of issuing commands to NIC 330.
- host 300 can select a command path that can efficiently transfer commands to NIC 330.
- a device driver 308 of NIC 330 running on the operating system of host 300 may select the command path.
- Driver 308 can dynamically determine whether to use the memory-based or low-latency command path for a respective command (i.e., on a command-by-command basis).
- Driver 308 may determine whether there is an outstanding command in command queue 312 and internal buffer 314 based on information from NIC 330.
- NIC 330 can provide the current locations of one or more pointers of command queue 312 to driver 308.
- NIC 330 may also provide statistics on how effectively internal buffer 314 is used.
- Driver 308 can determine whether to select internal buffer 314 for transferring the next command.
- driver 308 can speculatively determine that internal buffer 314 should have available capacity. Based on the determination, driver 308 may select internal buffer 314 for issuing a command if the current status of command queue 312 and internal buffer 314 meet the selection criteria. Otherwise, driver 308 may use command queue 312. Accordingly, NIC 330 can obtain a command from internal buffer 314 if possible. Otherwise, NIC 330 can obtain a command from command queue 312.
- FIG. 3B shows exemplary queues for facilitating dynamic command management in a NIC.
- the operations on command queue 312 can be based on the operations of a circular buffer.
- device 300 determines that a command 362 should be issued to command queue 312, device 300 can format command 362.
- Device 300 can then store command 362 in command queue 312 at the location indicated by a write pointer 352.
- Device 300 can then advance write pointer 352 to the next memory location.
- Advancing write pointer 352 can trigger a notification (or a“doorbell”) for NIC 330.
- Device 300 can write a plurality of commands to command queue 312 before advancing write pointer 352.
- the granularity of advancing write pointer 352 can be configured at device 300 (e.g., by a user).
- NIC 330 can determine that command queue 312 has a new command. If NIC 330 selects command queue 312 for processing (e.g., based on an arbitration process among the command queues), NIC 330 can read a command indicated by pre-fetch pointer 354 from command queue 312 and advance pre-fetch pointer 354. For example, if pre fetch pointer 354 represents the location of command 362, NIC 330 can read command 362 from command queue 312. When the data associated with command 362 is returned to NIC 330, NIC 330 can process command 362 and advance a read pointer 356.
- advancing read pointer 356 can include updating an application-visible copy of read pointer 356 according to a queue- specific policy.
- NIC 330 can continue to read commands from command queue 312 until the processing resources (e.g., the execution units described in conjunction with FIG. 2B) of NIC 330 have sufficient commands to execute.
- NIC 330 may stop reading commands if pre-fetch pointer 354 reaches write pointer 352 (e.g., if command queue 312 is empty). Since command queue 312 can be circular queue with a fixed size, device 330 may pause issuing commands to command queue 312 if write pointer 352 reaches read pointer 356.
- Write pointer 352 reaching read pointer 356 can indicate that command queue 312 is full and cannot accept a new command.
- Pointers 352, 354, and 356 can indicate a location or position in command queue 312.
- pointers 352, 354, and 356 can represent indices of command queue 312 (e.g., array indices) or memory pointers indicating memory locations.
- device 300 may determine that a command 364 should be issued to internal buffer 314 if device 300 determines or speculates that command queue 312 is empty. Device 300 can then format command 364 and store command 364 in command queue 312 at the location indicated by a write pointer 352. However, device 300 may not advance write pointer 352 and instead, may write command 364 into internal buffer 364 if device 300 determines or speculates that internal buffer 314 has sufficient capacity to accommodate command 364. Device 300 may perform the write operation using a PCIe based write operation. A write memory barrier, such as an SFENCE instruction, can be used between the respective writes to command queue 312 and internal buffer 314.
- a write memory barrier such as an SFENCE instruction
- NIC 330 Upon detecting the write operation in internal buffer 314, NIC 330 can advance write pointer 358. When NIC 330 selects command queue 312 for processing a command, NIC 330 determines that internal buffer 314 stores a command. Accordingly, NIC 330 reads from internal buffer 314 instead of issuing an interface-based read, such as PCIe read, to command queue 312. Upon obtaining command 364 from internal buffer 314, NIC 330 can advance pre fetch pointer 354.
- NIC 330 can track partial write operations to internal buffer 314 and advance write pointer 352 when the write operations within a block of internal buffer 314 have completed. If internal buffer 314 still includes data of a previous write operation, or command queue 312 has not been empty (i.e., pre-fetch pointer 354 has not been equal to write pointer 352) when operation 364 is issued, NIC 330 may drop command 364. Command 364 in command queue 312 can then operate as the backup command. When NIC 330 has available resources for executing another command, NIC 330 may obtain the next command from command queue 312.
- FIG. 4A shows a flow chart of a dynamic queue selection process for processing commands in a NIC.
- the host device of the NIC can obtain the last-known status of the command queue (operation 402). The device can then determine whether the command queue is empty (operation 404). If the command queue is not empty, the device may determine whether issuing commands to the internal buffer is speculatively beneficial (operation 406). For example, if the command queue is likely to be empty, issuing commands to the internal buffer can be speculatively beneficial.
- the device can maintain memory-based command path (operation 408) and continue to obtain the status of the command queue (operation 402). On the other hand, if the command queue empty (operation 404) or issuing commands is speculatively beneficial (operation 406), the device can switch to the low- latency command path (operation 410). It should be noted that the memory-based command path can be the default option for the device. Unless switched to the low-latency command path, the device can continue to use the memory-based command path to transfer commands to the NIC.
- FIG. 4B shows a flow chart of a dynamic command management process of a host device.
- the device can generate a command (e.g., in a format acceptable by a NIC of the device) insert the command into a command queue associated with the command (operation 432), and advance the device’s copy of the write pointer (operation 434).
- the device can then check whether the low-latency command path is selected (operation 436). If the low- latency command path is selected, the device can also insert the command into the NIC’s internal buffer associated with the command queue (operation 438).
- the device can advance the write pointer in the NIC (operation 440).
- the device can check whether the device’s copy of the write pointer has reached the read pointer (operation 442). If the write pointer has not reached the read pointer, the device can continue to generate a command and insert the command into a command queue associated with the command (operation 432). However, if the write pointer has reached the read pointer, the command queue can be full, and the device can refrain from issuing more commands (operation 444).
- FIG. 4C shows a flow chart of a dynamic command management process of the memory-based command path in a NIC.
- the NIC can select a command queue for obtaining a command (e.g., based on an arbitration process) (operation 452) and check whether a corresponding internal buffer includes a command (operation 454). If the internal buffer does not include the command, the NIC can determine whether there is a command in the command queue (operation 456). If there is a command in the command queue, the NIC can request the command from the command queue and advance the pre-fetch pointer
- the NIC can then wait for the requested command to be returned (operation 460). On the other hand, if the internal buffer includes the command, the NIC can obtain the command from the internal buffer associated with the command queue and advance the pre-fetch pointer (operation 464). Upon obtaining the command (operation 460 or 464), the NIC can advance the read pointer (operation 462).
- FIG. 4D shows a flow chart of a command management process of the low- latency command path in a NIC.
- the NIC can receive a command from the host device (operation 472) and determine whether the command queue is empty (operation 474). If the command queue is empty, the NIC can determine whether the internal buffer has available capacity to accommodate the received command (operation 476). If the internal buffer has available capacity, the NIC can insert the command into the internal buffer (operation 478) and advance the local copy (i.e., the copy of the NIC) of the write pointer (operation 480). On the other hand, if the command queue is not empty (operation 474) or the internal buffer does not have available capacity (operation 476), the NIC can proceed with the memory-based command path (operation 482).

Furthermore, driver 580 can speculatively determine that command queue 560 is likely to be empty and internal buffer 536 should have available capacity. Accordingly, NIC 520 can obtain a command from internal buffer 536 if possible. Otherwise, NIC 520 can obtain a command from command queue 560.
- Retrieval logic block 532 can determine whether an internal buffer 536 of NIC 220 includes a command.
- retrieval logic block 532 can obtain the command from internal buffer 536. On the other hand, if internal buffer 536 does not include a command, retrieval logic block 532 can obtain a command from command queue 560 in memory device 554. In either case, retrieval module 532 can advance a pre-fetch pointer. Execution logic block 534 can execute the command. Execution logic block 534 can then advance a read pointer.
